Using thieves oil to treat black mold

black mold thieves oilI  was recently contacted by a reader who has had terrible problems with black mold (Stachybotrys chartarum). If you’ve never heard about this problem, let me tell you that it is BAD stuff. Not only does it smell gross, but it is actually toxic, and it will cause you, your family and even your pets to get exceptionally sick if you don’t deal with the problem.

Thankfully, there are a few ways that you can combat and kill black mold with regular essential oils. For starters, you can spray pure tea tree oil on any place that has mold and it will kill the mold and end any smelly issues you have. But since black mold easily spreads to other parts of your home and creeps into everything, you’ll want to take extra precautions.

Thieves oil (which you might remember I gave you a simple recipe for a while back) is actually fantastic for combating black mold in the air and throughout your home. But for this use, you would not mix in the carrier oil (jojoba, almond, etc) but just use the combined essential oils from the recipe.

Most of the time, black mold spreads so aggressively that people end up having to move. But if that is not an option or you only have a small development of mold so far, you can diffuse thieves oil in your home. Usually, you should start with a 24 hour shock treatment and then diffuse daily for 15-30 minutes or once a month for 8 hours.

And of course, you can also diffuse thieves oil in your home to fight off anything you might not have yet discovered and keep your home germ free. If you’re starting off without a large mold buildup, you can begin with an 8 hour diffusion and then follow with the 15-30 minute or 8 hour monthly treatments.

You’ll need to diffuse the oils on every floor of your home, and starting with a basement or bottom level (where mold often starts) and working your ways up usually works best.

Cold air diffusion is now said to be one of the most efficient ways to distribute the oils evenly in your home and also makes sure you don’t add any moisture to the room. You can find several examples of cold air diffusers on this website.  I have no affiliation with them and don’t know if there prices are fair. I just found them via a google search and they had a lot of good information about diffusers so I think it’s a good place to get started if you are looking to buy one of these.

Another cheaper alternative would be to put 4-8 drops of thieves oil onto a cotton ball and place it on the air vents in your home. You can also put them on your return air vent so it will filter into your air system as well. To clean your dryer, add 2 drops to a wet washcloth and run your dryer for several minutes. You can also put a few drops into your washing machine and just run a rinse cycle.

Thieves oil will actually kill the mold in your home over time but you have to continue using it. You won’t likely want to be in the room when you’re diffusing because of the cinnamon and clove oils. They have a very “hot” feeling to them and can irritate the skin and mucus membranes. Children and pets should also definitely not be in the room because these types of oils in such small bodies is bound to cause irritations.

For the same reason, if you put the oil on your skin or ingest it, you’ll want to do a small test area first. If you apply it to your body (rubbing a small amount on your chest for example), you’ll probably want to dilute it with something like almond, jojoba or olive oil. Use 1 part of the essential oil mix to 4 parts carrier oil and only apply it in small amounts, especially at first. A little bit will go a long way.

Or you can also apply it “neat” to your feet (just a couple drops) without mixing it with any other oils. I do the latter and don’t notice any burning when I put it on…but I don’t touch the oils with my fingers and have pretty tough skin on my feet.

You can also dilute it 1 part thieves oil to15 parts carrier oil for massages but the smell of it may be too hard to handle. It’s very intense.

If you want to drink it, just add a couple drops to a full glass of water. You can do this several times throughout the day. And if you happen to have a headache, add a drop of thieves oil to your tongue and press it to the roof of your mouth. I’ve even done the latter with migraines and it made my headaches almost unnoticeable.

One of the most important things to remember when dealing with toxic black mold is that it will grow in and on just about everything…and it is often very hard to get rid of. Glass, and wood metal surfaces can be cleaned with a solution of water and thieves oil (add a teaspoon to every gallon of water) or just tea tree oil. But skip the bleach, especially on wood, because it will not dry out quickly enough and the mold will start all over again. Anything with fabric (furniture, mattresses, clothing), paper or porous materials harbors mold spores so just diffusing could take a very long time to eliminate the problem. In fact, you’ll need to have these things professionally cleaned and/or dispose of them.

      Oils must be cold diffused. The diffuser I use is so pretty…shaped like a flower and lights up. I don’t burn candles or use artificial fragrances in my home any more, and everyone who visits comments on how good it smells!

      • Kimberly says

        We have a busy home and are battling mold in our basement. I need a recipe to diffuse oils on both levels of our home with us and our pets being present. What oils do you use that are pleasant to smell and not irritating? Can I ask where you got your cold diffuser at? Thank you!!

    I don’t know if you visited this website- and if you haven’t been there, check it out. You can’t burn the oils, as it will change the molecular properties, and you need a nebulizing diffuser to really work. (The ultrasonic ones don’t get enough oil in the air.) The thieves blend does work, but you do have to use pure oils, not synthetic. Thanks for a great post on a non toxic solution!

  2. Chrissy Mann says

    When toxic mold dies, it leaves behind a casing which contains mold spores. These mold spores emit what are referred to as mycotoxins. When mycotoxins are inhaled or ingested, they are potentially deadly and are to be avoided if a person does not want to suffer toxic mold poisoning. Thieves oil DOES NOT treat or manage the spores or the mycotoxins. Thieves oil may kill the mold but it leaves behind the deadlier mold spores and mycotoxins that can be released and create vast biohazardous conditions. Our company has discovered a beneficial biological formulation that is 0’s on Material Safety Data Sheets and it consumes the mold, the mold spores and the mycotoxins leaving the property safe, healthy, and environmentally friendly.

    • Tiffany says

      There is actually research that indicates that thieves oil can and DOES kill mold spores. And that even after treatment has ended, spores continue to die. The case study information can be found here:

      But as far as mycotoxins are concerned, I think tea tree oil is said take care of them. Which is why I recommend using both.

      I think everyone who experiences black mold problems needs to research the available options and absolutely do testing to be certain that the mold is indeed dead and gone.

      Dear Chrissy,

I have a Mold problem in my home in an area we are unable to get at, I have been using a cold air diffuser running Thieves oil in it at night to kill the mold…but didn’t realize about the Mycotoxin’s from the Dead Mold. I would GREATLY Appreciate any information You or anyone could Please give me!!! Thanks, Pam :o))

      Hello Chrissy Mann,
      Please what is this product that is “… a beneficial biological formulation that is 0′s on Material Safety Data Sheets and it consumes the mold, the mold spores and the mycotoxins leaving the property safe, healthy, and environmentally friendly.”
      & where can it be purchased?…
      Thank you.

        Hi Laura,
        The Mold Remedy product I had mentioned in the post is the product we use when we perform mold remediation services and unfortunately not for sale. We sold this formulation five years ago but found out after a lot of study that there is more to mold remediation than meets the eye. Our product consists of 100% naturally occuring probiotic microbes 18 families and over 125 species at a minimum are in the product. The mold is the microbes food source and mold and mold spores are consumed until there is nothing left. The product is very effective and we have treated everything from homes to 350,000 sq.ft.theatres in Branson, MO with 100% success. It does take a lot more than just spraying the Mold Remedy. A lot of people we were selling the product to were using unsafe methods in treating their own spaces like not using proper personal protection devices (masks, resperators, hazmat suits, gloves etc…)and we could not in good conscience allow this. After a lot of thought and study my husband Shane obtained several certifications (listed on our website continues his studies to this day. I welcome you to look over our website and our phone numbers are listed there if you would like to contact us with any questions you may have.
        Thank You,
        Chrissy Mann

           And how do we know this is not just an attempt at getting people to look unfavorably on natural remedies in favor of spending their money with your company, for your services?

    • Pam says

      Yes, I would like to know what the product is or where I can buy it that Chrissy Mann is talking about! Please e-mail me & give me the information on where to buy this biological formulation that is 0′s on Material Safety Data Sheets. Thanks so much, Pam

    my wife diane is so hypersensitive to the black mold the smallest contact with it her blood pressures go sky high i have remediated almost the whole house but we feel there is still some there, do u think the thieves will help Thanks, Wally

    • Tiffany says

      I would recommend testing out in an isolated space first using a diffuser and then going from there. It sounds like you’ve already killed & gotten rid of any traces of mold in your house, but the thieves should keep it from coming back as well as eradicate anything you can’t see. Thieves oil can be very aggravating to the mucus membranes so you do want to test it out in the air first.
      There is more information about treating your home with thieves here:

    i just ran across your very helpful site. we have a mold issue in our home and are undergoing renovations to correct it. in addition, i want to use thieves oil for diffusion and cleaning. i, too, have migraines and am interested in your suggestion below. i ran across another sentence in your information that seems to contradict ingesting it. would just like to clear this up?

    “If you want to drink it, just add a couple drops to a full glass of water. You can do this several times throughout the day. And if you happen to have a headache, add a drop of thieves oil to your tongue and press it to the roof of your mouth. I’ve even done the latter with migraines and it made my headaches almost unnoticeable.

    “But be very cautious about anything that suggests putting thieves’ oil in your mouth or otherwise ingesting the ingredients.”

    thank you!

    • Tiffany says

      I have been ingesting thieves oil for about a year now and never had any adverse reactions. But that does not mean that everyone is the same. These are extremely powerful oils that can burn the skin when applied topically. So I must caution anyone who decides to use them internally to do so with extreme caution until they know they will not have any problems. I put undiluted TO in my mouth to combat the migraines and also put it on my toothbrush daily to help keep my teeth and gums healthier.
      Sorry for the confusion, but basically I guess I should have said “try this at your own risk” instead. :)

      Best of luck with the Thieves!

  5. Lynne says

    gotcha, thank you…i’m game to try it. do you have a source for larger quantities of the ingredient oils for thieves? it’s REALLY expensive to buy it all in those little bottles.
    thank you!

  6. Marion says

    Theives Oli
    Can u please tell me is it known under a different name in the UK to USA? My herberlist hadn’t heard of this oil. She checked her book but still no luck.
    I’d be really grateful if you are able to advise me
    Many Thanks

  7. Marion says

    Can anyone tell me where I can purchase Theives Oil. My local herbalist has never heard of it. Is there a web site best for buying this oil? I’m desperate to try it. I live in Cornwall United Kingdom.
    Look forward to any suggestions. Thanks

    Calling it “Thieves” oil is an insult to those who invented it. The Roma or what most people think of as “gypsies”. It’s very racist and rude. So they helped stop the bubonic plague only to have their product sold by others with such a horrible name. RENAME IT!

    • says

      I actually didn’t come up with the name of the product. There’s another company online that markets it under this name — and if one renames it at this point, there will be a lot of people that no longer know what anyone is talking about.

      But I actually think the oil came about during times of the plague when people were dying in droves…and the thieves and burglars in the area began using this combination to outlive others. Hence that is where the name came from. Whether those thieves were Roma or not, I really don’t know.

  9. Renee says

    I don’t know if you monitor this any more, but if you do, we are about to use thieves in our bedroom for mold. We are closing it off for intense diffusing. My question is, do I need to remove the books and photos and tv? Will the oil diffused intensely in there damage them?

  10. ProudSCresident says

    I use Thieves oil, spray, cleaner, soap, toothpaste, mouthwash, and hand sanitizer. I’ve been studying and using the oils for over a year now, and I’ve not had a single sick visit to the doctor! I find them amazing! I diffuse Thieves oil in my house to keep down mold and germs. When I was on vacation this past week, I took my diffuser with me to detox the condo.
